Dosage adjustment in patients 12 years of age and older with renal impairment or undergoing hemodialysis is recommended, as follows (see dosing recommendations above for effective doses in each indication): TABLE 1.

Notes: Monitor for dizziness or double vision. Moderate Kidney Problems (CrCl 30-59 mL/min): Dose Adjustment: 400-1400 mg/day BID; How Often to Take: Twice a Day; Notes: Your doctor will decide the Loading dose of 300–400 mg in patients who have never received gabapentin. Maintenance dose of 200–300 mg after each HD : session and increase according to tolerability. Absorption of gabapentin is solely dependent on LAT that are easily saturable, resulting in dose-dependent pharmacokinetics. As the dose of gabapentin increases, the area under the plasma concentration–time curve (AUC) does not increase proportionally. Detailed Gabapentin dosage information for adults and children. Includes dosages for Restless Legs Syndrome, Epilepsy and Postherpetic Neuralgia; plus renal, liver and dialysis adjustments. Usual initial gabapentin dose: 300mg q8h. Usual maintenance dose: 300-600mg q8h. Maximum dosage/day: 3600 mg. [15-29]: Dosage range: 200-700mg/day. [<15]: 100-300 mg/day. Use lower end of this range for CRCL <7.5 ml/min. TABLE 1.

Renal excretion: 100% unchanged: 92–99% unchanged: Suggested dosing schedule: Three or four times daily/ Two or three times daily: Usual dose: 900–3600 mg/day: 150–600 mg/day: Time to effective dose using recommended titrations: 14 days: 5–7 days: Gabapentin dosing in renal impairment (creatinine clearance, mL/min) 50–79 Table 1 shows maximum recommended dose of gabapentin in renal impairment: Table 2 shows the maximum recommended dose of pregabalin in renal impairment: In this scenario you are carrying out an audit of gabapentinoid prescribing in your work area, to ensure that the doses prescribed in renal impairment are safe and appropriate. 3 days. The recommended maintenance dose of NEURONTIN in patients 3 to 4 years of age is 40 mg/kg/day, given in three divided doses. The recommended maintenance dose of NEURONTIN in patients 5 to 11 years of age is 25 mg/kg/day to 35 mg/kg/day, given in three divided doses. NEURONTIN may be administered as the oral solution, capsule, or tablet, or In patients with normal renal function, the maximum dose of gabapentin is 3600mg daily in divided doses. However, gabapentin is renally cleared and so the dose needs to be adjusted according to the GFR. For patients on dialysis, the recommended dose is 100-300mg post dialysis on dialysis days only. Max dosage 3600mg if patient already on gabapentin; Taper dose > 7 days to discontinue; Pediatric Dosing Partial seizures. Adjunct for partial seizures with out secondary generalization in patients> 12yo with epilepsy; also adjunctive therapy for partial seizures in patients 3-12 years <3 years: Safety and efficacy not established Drug dosing requirements for antihypertensives in patients with chronic kidney disease are listed in Table 4. 4, 5 Thiazide diuretics are first-line agents for treating uncomplicated hypertension The half-life of gabapentin immediate-release formulation is 5–7 hours in patients with normal renal function and is prolonged up to 52 hours in patients with CrCl<30 mL/min. 26 The half-life of pregabalin is 16.7 hours in patients with CrCl 30–59 mL/min, 25 hours in patients with CrCl 15–29 mL/min, and 48.7 hours in patients with CrCl<15 TABLE 1. NEURONTIN Dosage Based on Renal Function; TID = Three times a day; BID = Two times a day; QD = Single daily dose * For patients with creatinine clearance <15 mL/min, reduce daily dose in proportion to creatinine clearance (e.g., patients with a creatinine clearance of 7.5 mL/min should receive one-half the daily dose that patients with a creatinine clearance of 15 mL/min receive).
